Definitions

• Data adapter for communication devices for the remote transmission of user data, in particular packet and / or voice data
• the invention relates to a data adapter for communication devices for the remote transmission of user data, in particular packet and / or voice data, according to the preamble of patent claim 1.

• the devices can also be connected to wireless telecommunications networks using PCMCIA cards.
• a notebook can be connected to the GSM network in a known manner via a PCMCIA card and a GSM handset (GSM cell phone).
• GSM cell phone GSM cell phone
• Such a device arrangement can be used regardless of location, but it cannot be used for different user-specific applications. For example, it is not possible that the user cannot install his own user-specific network for remote transmission of user data, regardless of the telecommunications network.

• the data adapter provided with a V.24 interface to the communication device, for example, allows data transmission rates of up to 64 kbit / s, the transmission rate of an ISDN user data channel.
• the decision as to which of the two air interface architectures is to be used is preferably made by the user of the data adapter in accordance with the
• the program modules necessary for the operation of the data adapter can be assigned either to the data adapter itself or to the communication device according to claims 5 and 6. While the procedure according to claim 5 is suitable for personal computers, notebooks, PDA devices, etc., the procedure according to claim 6 is advantageous for printers and fax machines.
• FIG. 1 shows the principle, based on the OSI / ISO layer model [cf. (1): Struktursability - LiebeInstitut, Jg. 48, 2/1995, pages 102 to 111; (2): ETSI publication ETS 300175 -1. , , 9, October 1992] based on the construction of a data adapter DA, for example a PCMCIA card or connection device, for communication devices KE for the remote transmission of user data, in particular voice and / or packet data, based on an application (scenario for the remote transmission of voice and / or packet data) , in which, for example, a first communication device KE1, designed as a personal computer (PC), has a first data adapter DA1, designed for example as a DECT data adapter, and a second communication device KE2, designed for example as a personal computer (PC), has a second device, for example, designed as a DECT data adapter Data adapter DA2 for the remote transmission of user data, for example packet data, are connected to one another wirelessly.
• the two devices are arranged so far apart, for example, that the transmission range specified in the DECT standard or that in principle possible according to the DECT standard is not exceeded.
• the two devices are preferably not in the radio range of a DECT base station to which the devices have access authorization.
• a data adapter of the two data adapters DA1, DA2 - for example the first data adapter DA1 - is operated or operated in a DECT fixed part-specific mode, the FP mode (Fixed Part) controlled in a first control state STZ1 and the other data adapter - for example the second data adapter DA2 - operated in a DECT handset-specific mode, the PP mode (Portable Part), or controlled in a second control state STZ2.
• the data adapter DA1, DA2 contains, for example, a data interface DSS designed as a serial V.24, RS232 or USB interface (Universal Serial Bus), via which the data adapter DA1, DA2 is connected to the respective communication device KE1, KE2.
• the data adapter DA1, DA2 control means STM and data transmission means DUM are included.

• control means STM contain an "Interworkmg Unit” layer (IWU layer) IWUS, a first protocol module PKM1 designed as a DECT-FP protocol stack, a second protocol module PKM2 designed as a DECT-PP protocol stack, a physical layer (PH layer ) PHS and possibly a program module PGM. Since this program module PGM can alternatively also be contained in the communication device KE1, KE2, the program module PGM is shown in dotted lines in the FIGURE.

• the IWU layer IWUS is connected on the one hand to the data interface DSS and on the other hand - depending on the mode in which the data adapter DA1, DA2 is to be operated or the control state STZ1, STZ2, e.g. connected via an FP / PP switch - connected to the first protocol module PKM1 or the second protocol module PKM2.

• the data adapter DA1, DA2 can be controlled (configured), for example via the FP / PP switch, in such a way that the data adapter DA1, DA2 is designed or functions either as a base station or as a handset. If the egg 7 ne data adapter is configured as a base station and the other data adapter as a handset, then the handset can use the known DECT registration procedures over the air interface ⁇ be notified to the base station. With the PGM program module, initialization and control of the DECT registration procedures is also possible. After registration, the wireless remote transmission of user data between the communication devices KE1, KE2 is possible.

• a data adapter If the data adapter is operated in FP mode in this case, i.e. a base station is connected to the local network, then another communication device, e.g. a telephone, which is connected to a data adapter operated in PP mode or with a conventional DECT handset via the communication device connected to the local network, voice data is transmitted either via "interworking" from the local network (LAN) to the ISDN network or as Internet telephony .
• the data adapter connected to the notebook can be switched from FP mode to PP mode. If another base station is directly or indirectly connected to the local area network (LAN), then packet data can be transferred remotely with the notebook for printer or LAN server access (Stw.: Internet sessions).
